Thirteen years ago, boozed-up Harry Graham (Robert Mitchum) savagely murdered his wife. A witness - his horrified little son - provide the testimony that put him behind bars. Now Harry is out, living in a seedy trailer park with a loving woman (Brenda Vacarro), when a reminder of his past shows up: his now-grown son (Jan-Michael Vincent). As father and son circle each other, as past and present intersect, tension grows until it finally erupts in a shock of violence. In a powerful performance, Mitchum brings enigmatic menace to the role of Harry Graham.
